Create Chord WAV Files

Source: R/output_functions.R
chord_WAVs.Rd

Creates WAV files for inversions of a chord between two notes

Usage

chord_WAVs(
  chord,
  keyboard_map,
  lowest_note = 48,
  highest_note = 84,
  output_directory = "~/Multisample",
  signal = "tria",
  duration_sec = 1,
  velocity = 100,
  sample_rate_hz = 48000,
  bit_width = 24
)

Arguments

chord

a numeric vector with the scale degrees for the chord

keyboard_map

the keyboard map for the scale

lowest_note

the lowest MIDI note number to use, default is 48.

highest_note

the highest MIDI note number to use, default is 84.

output_directory

character, default "~/Multisample". This will be created if it does not exist.

signal

the seewave signal type, default is "tria"

duration_sec

how long to hold each note, default = 4

velocity

MIDI velocity, default = 100, max is 127

sample_rate_hz

sample rate in hz, default = 48000

bit_width

bit width of samples, default = 24

Value

the full path to output_directory

Examples

if (FALSE) { # \dontrun{
eikosany <- cps_scale_table()
eikosany_chords <- cps_chord_table(eikosany)
eikosany_map <- keyboard_map(eikosany)
chord_degrees <- eikosany_chords$degrees
for (i in 1:length(chord_degrees)) {
  chord <- as.numeric(unlist(strsplit(chord_degrees[i], ":")))
  folder_name <-
    paste0("~/eikosany-chords/chord-", gsub(":", "-", chord_degrees[i]))
  print(paste0("generating WAVs in folder ", folder_name))
  chord_WAVs(
    chord,
    keyboard_map = eikosany_map,
    lowest_note = 40,
    highest_note = 80,
    output_directory = folder_name
  )
}
